Man, I could post a buddie's breakdown on fin configurations here. But my beginner advice is following...I am sure the experts here will chime in!!!
I started with the broadcast this season to get me to ropeless. Rode with only the center fin until getting hooked up with a new oogle. I had tried the 2 outside fin configs but the board was really locked in...
The single fin config made the board alot more maneuverable and lose for me...I liked it alot more because I could move around in the pocket and learn more from this configuration.
